`filterStackFrame` was called with a sourceURL that didn't reflect the original sourceURL. This breaks once you try to use `findSourceMapURL` on the given sourceURL since the encoding would be off.

filterStackFramewas called with a sourceURL that didn't reflect the original sourceURL. This breaks once you try to usefindSourceMapURLon the given sourceURL since the encoding would be off.Mostly stood out when reading source that the encoding/decoding wasn't consistent.
ReactServeralways usesencodeURIbutdevirtualizeURLdid not applydecodeUR.ReactReplyClientdidn't encode at all. It's important thatrsc:URLs have a predictable format so that frameworks can retrieve the original sourceURL reliably.
